To all whom it may concern:

Be it known that I. Lnsmn R. N. CAR- VALHO, a citizen of the United States. residing at Toledo, in the county of Lucas and State of Ohio, have invented new and useful Improvements in Receptacle Closures, of which the following is a specification.

My invention relates to a receptacle closure adapted for usewith bottles, jars or other containers. More particularly, it relates to a type of closure which when first applied to a container is secured in sealing position by attaching means wlnch are destroyed or. rendered ineffective when the container is first opened, but the closure 1tself is adapted to be repeatedly used as a temporary' closure, which is often desirable,

while the contents of the container are being used up.

An bject of the invention is to provide an improved closure or cap of this type which after being originally removed from the container may be repeatedly used to seal the container. -For this purpose, the cap is provided with attaching means for temporarily holdin it in sealing posltion independently of t e means by which the closure is originally attached to the container. By this provision, the closure cap can be repeatedly used and serves to tightly seal the container after it has been originally opened. At the same time,'the original sealing means havin been destroyed, notice is given to the user that the closure as originally applied to the container has been removed.

an improvement of the invention disclosed in my co-pending application, Serial Number 511,392, filed October 29, 1921 In the accompanying drawings:

Figure 1 is a part sectional elevation of a container and closure therefor, embodying the principles of my invention.

Figure '2 is a section at the line 11-11 on Figure 1.

Fi re 3 is an elevation view illustrating the c osure or cap being originally applied to the container.

Figure 4 is a similar view with the cap secured in position on the container.

Figure 5 shows a modified form of container.

Figure 6 is a section at the line VI'VI on F1 re 5.

Re erring particularly to Figures 1 to 4,

a closure or ca is shown applied to a container herein s own as a glass bottle. The cap as illustrated comprisesa cover portion 10 and a flange portion 11 united by a seam 12. A gasket 13 of cork or other suitable material is' fitted within the cap and when the cap is applied to the container forms an effective seal; When the cap is originally applied to the container, a tight seal is effected by applying a downward pressure thereto at the seam' 12, so that the gasket 13 is compressed as shown. The cap is secured in such position by bending the lower edge 14 inwardly to form a flange engaging a shoulder 15 on the neck of the container.

A score line 16 is formed in the flange 11 a short distance above the lower edge and extends the entire circumference of the ca thereby providing a removable strip 17. One end of this strip may be extended to form a finger piece 18. By grasping this finger piece, the rip strip 17 may be torn off, thereby permitting the cap to be removed from the container simply by with drawing it in an upward direction. The construction andoperation as thus far described may be substantially the same as more fully set forth in my co-pending application above referred to.

After the original attaching means has been destroyed by tearing off the strip 17, the cap may .still be used as a temporary closure until the contents of the container have been used up. In order that the cap may be tightly held in place and form a The present invention is in the nature of close seal during such use, the following construction is employed: The neck portion of the container is formed with bayonet slots or recesses comprising vertical ortions 19 having lateral extensions 20 at t eir lower ends. The cap is provided with inwardly projecting coo crating lugs 22 which i may be formed by in enting the cap.

After the original locking strip 17 has been torn off and the cap removed, the ca may be replaced and secured in sealing pos1- tion byj'rotating it to carry the lugs 22 into the slot extensions 20. The extensions 20 provide shoulders 23, beneath which the lugs 22 engage, thereby firmly holding the cap in position. The surfaces 23 are preferably slightly inclined, the inclination being suflicient to draw the cap down firmly into position as it is rotated and thus insure atight seal. It will be observed that with this conribs 25: These ribs are undercut to form slots 20 and shoulders 23 as described in con nection with Figures 1 to 4.

Modifications maybe resorted to within the spirit and scope of my invention.

What I claim is:

1. The combination with a container, of a cap therefor comprising an attaching means by which the cap is originally attached to the container, said attaching means being separable from the body of the cap to permit removal of the cap, a second attaching means by which the cap may be attached to the container after the original attaching means has been removed, said second attaching means being maintained out of attach ing position during the original positioning and attachment of the cap to the container.

2. The combination with a container, of a cap therefor comprising an attaching ineans by which the cap is originally attachedto the container, said attaching means being separable from the body of the cap to permit removal of the cap, a second attaching means by which the cap may be attached to the container after the original attaching means has been removed, said second attaching means comprising interlocking parts carried by the cap and container respectively' and maintained out of interlocking relation during the original positioning and attachmentof the cap to the container.

3. The combination with a container, of a cap -therefor comprising an attaching means by which the cap is originally attached to the container, said attaching means being separable from the body of the cap to permit removal of the cap, a second attaching means by which the cap may be attached to the container after the original attaching means has been removed, said second attaching means comprising interlocking surfaces on the cap and container respectively, said surfaces being held out of engagement during the original placing and attachment of the cap to the container and brought into operative relation by a rot-ative movement of the cap on the container.

4. The combination of a container comprising a neck, a closure cap therefor comprising a flange portion extending downward to surround the neck, means for originally securing the cap in position, a second securing means for holding the cap in posi- 4 being arranged to be held out of contact during the original placing "and securing of the cap on the container.

5. The combination of a container'comprising a neck, a closure cap therefor comprising a flange port-ion extending downward to surround the neck, means for originally securing the cap in position, a second securing means for holding the cap in position on the container after it has been removed, said second securing means comprising a bayonet slot in the neck of the container, said slot including a vertical portion extending downward from the lip of the container and a laterally extending portion, and a detent on the cap which moves downward in said vertical portion of the slot dur ing the original placing of the cap and is maintained in said vertical portion of the slot while the cap is originally secured, said detent being arranged to enter said lateral portion of the slot for locking the cap in position after the cap has been originally removed from the container and replaced.

6. The combination of a container comprising a neck portion formed with an annular shoulder, a cap therefor comprising a top cover portion and a flange portion, the flange portion including a removable strip having its lower edge turned inward beneath said annular shoulder for originally securing the cap to the container, a second securing means comprising a detent formed in the cap, and a cooperating bayonet slot formed in the neck of the container, said slot comprising-a vertical portion to receive said detent during the original placing and securing of the cap on the container, and a lateral extension to receive said detent and lock the cap in position when replaced on the container after said strip has been removed.
